,-V-'Ivhe 'fractureleucng means fconsists Y-ofgra windlassshat ZLproVided with a crank 25, the

shaftbe'ing mounted rotativelyin .a bracket Q26 which is detachably mounted on the Aside memlug "l1 that 'embraesthe" corresponding Vside member and has a pin 28 that iits in a corresponding opening in the side member whereby the bracket is held from moving longitudinally on the frame. By pressing the sides of the bracket 26 inwardly so as to detach the lugs from the side'members the bracket together with the windlass isV readily removed.

The yielding extension means consists of a second windlass shaft 29 which is rotatively mounted in the side members I and 2 of the frame and is conveniently disposed in the frame at a point located between the rear end of the frame and 4the bracket 26. Y

One endof the windlass shaft 29 has secured.

iTI)

A side member 2 at such point thereon that 'the spring is stretched when the h ook34 is in operable connection with the rim of the wheel,. so that the wheel is thereby yieldingly held from rotation. Y-

Preferably, the ring 9 is made so as to admit of adjustments whereby its` diameter isenlarged or decreased to suit the type of patient under treatment.

forated and overlap each other and may conveniently be secured together in adjusted positions' by inserting the pivotfviil through the arm 4 and registering perforations in the overlapping ends. The anchor plate I2 is .secured to the hoop 36 so as to befsupported thereby, and a tubular cushion`3'l is'arranged so as to substantially encase the hoop. Y Y 'A Y In using the invention the injured leg 38 is inserted vthrough the ringv 9 into' position between the side members and arms of theV frame. An ankle strap 38 is then applied tothe injured mem.- ber and connected to the windlass shaft 24 by a Ycable 40 so thatby turning the crank 25 the cable is wound upon the windlass shaft and more or less tension is applied to 'the injured member as required to. reduce the fracture. Subsequent to the fracture reducing operation connection is made between the windlass shaft 29 and the injured member by means 4of a cable 4I,'ban`dag'es 42 and a spreader 43`of any suitable. type or by such other expedient as the attending surgeon may elect, Vso'that upon turning o1 the windlass shaft by manipulation of thehand-Wheel 30 the desired amount of traction is appliedto the patients leg. 'I'he ankle strap is then removed and the bracket 26 with the windlass V24 is disrnounted from the frame.

By connecting the hook rod 32 with the rim of the hand-wheel 30 the windlass shaft 29 is yieldingly restrained from unwinding movement in opposition to the tension of the spring 33.

The foot is suspended from the top of the arch 22 of the anchor frame by applying aj suitable bandage 44 or other convenient connection between the foot and arch.

i 1. A surgical appliance consisting of a splint frame having spaced side members, a windlass and its complemental supporting bracket remov- Suoh ring is formed of' a'circular vspring metal hoop 36, the ends of which are perably secured on said frame, an extension means consisting of a second windlass mounted in said frame provided with operating means therefor, a retractive mechanism operatively associated with said operating means, and supporting means for said frame.

2. In a fracture splint, a frame, two windlasses mounted in juxtaposition with each other upon said frame, one of which is removable therefrom and the other havingl a yielding mechanism, means for independently operating and separately connecting said windlasses with an injured member positioned in said frame, and means for Y supporting said frame.

3. In a fracture splint, a frame, a fracture reducing means consisting of an unyielding windlass provided with a supporting bracket removably mounted on said frame, a traction means consisting of a second windlass mounted in said frame independently operable and arranged in juxtaposition with the first mentioned windlass, said second windlass having an adjustable yielding mechanism, and means for separately connecting said windlasses with an injured member in said frame.

4. In a fracture splint, a frame having a cushioned head member, a fracture reducing means consisting ,of a windlass and its complemental bracket, said Vbracket being removably mounted on said frame, means for connecting an injured member positioned in said frame with said windlass, and yieldingretractive means in connection with said frame applicable to said injured member and independently operable with respect to said windlass. -Y

5. In a fracture splint, a frame having spaced side members, a windlass having a ysupporting bracket detachably secured to said members, a second windlass mounted in said frame in juxtaposition with the other windlass and provided with an operating member, and a retraotive mechanism in connection with said frame and operatively associated with said operating member.

6. In a fracture splint, a frame, a traction means consisting of a windlass mounted in said vframe provided with an operating member, and a retractive mechanism inV connection with said frame operably associated with said member. f

7. In a'fracture splint, a frame having spaced side members, an anchor frame removably positioned upon and having longitudinal adjustment with respect to said members, a traction means 'in connection with the frame consisting of a windlass and its complemental operating member,

Va retractive mechanism in connection with said frame operably associated with said operating member, and means separately connecting said anchor frame and said windlass with an injured member positioned in said frame.
